How do I create texture that resembles texture of human body?
Since it seems you found it useful, I am re-posting my comment as an answer:

For the dimpling use a combination of a Displace Modifier and some bump in your material. For the skin material add an SSS Shader to your glossy+diffuse mix. A skin texture image into the Diffuse color input would help too. For the ripple you can use a Cloth sim like in this tutorial. or a Soft Body sim like in this tutorial. Finally here is a Soft Body tutorial specifically for belly ripple, lol - although it is in Spanish. Good luck!
